APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday April 6, 2009 (MJD 54928) ---=== OBSERVING TEAM ===--- Stephanie Snedden Viktor Malanushenko Nathan De Lee (MARVELS) ---=== OBSERVING PLAN ===--- 6 Apr 2009 54928.0 0.84 MARVELS 9.5 hours ---=== OBSERVING SUMMARY ===--- Clear sky, bad seeing. We observed one Marvel_Pre and five Marvels plates: Marvels plates: Cart 8, plate 3089A & B Cart 3, plate 3417B Cart 4, plate 3416B Cart 9, plate 3358A & B Cart 6, plate 3217A Marvel_Pre plate Cart.7 plate 3349. There is an apparent dead fiber on cartridge 4, side B, spectra 91,92 - Fiber 5, yellow, blue, cyan Technical notes: -- MARVELS Gang Connector worked quite good. Thanks, Dan! -- Each time we shoud run command 'axis init' twice time on telescope laptop. Because after first command the Alt and Rot went out of closed loop. ---=== OBSERVING LOG ===--- Afternoon: ---------- During afternoon checkout, it took several tries to clear the az brake, but was okay after it finally cleared. The 30 deg. alt fiducial was not read going up or down. The 45 deg alt fiducial only read going down. No change was made to spectro focus. 01:30Z enclosure off Night: ----- 01:38Z started Cal.sequence Cart.8 plate 3089A 02:13:41Z gotoField, used FK5 02:21Z 50min exposure.
